imx9: scmi: Print CPU part number name
Decode the CPU part number from PART_NUM fuse and print it in CPU name.
For iMX95 and iMX952 Part number fuse is defined as:
[7:6] : Package description
[5:2] : Segment
[1:0] : Number of A55 cores
For iMX94, the PART_NUM[7:0] fuse directly reflects the
part number value.
